Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, a hemming device for knee pad production comprises a sewing machine body 1, a workbench 2 is fixedly connected to the sewing machine body, a working chamber 3 and an adjusting chamber 4 are arranged in the workbench 2, a swing shuttle is arranged in the working chamber 3, a horizontal threaded rod 5 is arranged in the adjusting chamber 4, two ends of the threaded rod 5 are rotatably connected with two side walls of the adjusting chamber 4, a moving block 6 is connected to the threaded rod 5 in a threaded manner, moving rods 7 which are symmetrical about the axis of the threaded rod 5 are arranged on two sides of the moving block 6, the moving rods 7 are rotatably connected with the moving block 6, an adjusting plate 8 is rotatably connected to the other side of the moving rods 7, one side of the adjusting plate 8, which is far away from the threaded rod 5, is designed into a cambered surface, so that the product quality caused by friction between a right-angle edge and a knee pad can be effectively prevented, the adjusting, one end of the threaded rod 5 penetrating through the side wall of the adjusting chamber is connected with an adjusting knob 9.

Specifically, a cavity 10 is arranged in the adjusting knob 9.

Specifically, one end of the threaded rod 5 connected with the adjusting knob 9 is located in the cavity 10 and is in sliding connection with the cavity 10, and one side of the end portion of the threaded rod located in the cavity 10 is fixedly connected with a limiting strip 11.

It is worth mentioning that the cavity 10 lateral wall is equipped with spacing 11 complex recesses, spacing 11 and recess sliding connection, thereby can realize that adjust knob 9 can take place to slide and can drive threaded rod 5 together to rotate when adjust knob 9 rotates with threaded rod 5, the recess communicates with cavity 10, the recess does not communicate with each other with the external world and can ensure that spacing slides all the time in the recess can not separate with the recess, and then realize that threaded rod 5 can not separate with adjust knob 9 and get together spacing effect.

Specifically, the adjusting knob 9 is close to one side fixedly connected with limiting sleeve 12 on the workstation, and the inside wall of the limiting sleeve 12 is provided with a plurality of regularly arranged first bulges.

It is worth mentioning that one side that workstation 2 is close to adjust knob 9 is provided with annular spacing groove 13, and spacing groove 13 axis is in same straight line with spacing sleeve 12 axis, is equipped with on the spacing groove 13 lateral wall with spacing sleeve 12 matched with second protruding, spacing groove 13 and spacing sleeve 12 cooperate and can play and carry out spacing effect to adjust knob 9 to make threaded rod 5 unable rotate and then realize carrying out spacing effect to the workstation.

The working principle is as follows:

the utility model discloses during the use, if the knee-pad can not be well at 2 during operations of workstation, pull out adjust knob 9 towards the direction of keeping away from workstation 2, break away from the contact until limit sleeve 12 and spacing groove 13, stopper 1 time rigid on threaded rod and threaded rod 5 in this process, and respectively with cavity 10, the recess takes place to slide, rotate adjust knob 9 as required again this moment, will drive fixed connection's threaded rod 5 when adjust knob 9 rotates and rotate with it, threaded rod 5 is for rotating around self axis between 4 lateral walls of control chamber, movable block 6 with 5 threaded rod threaded connection is because both sides all are connected with carriage release lever 7 and can't rotate around 5 axes of threaded rod, consequently will remove along 5 axes of threaded rod.

When the moving block 6 moves, the moving rod 7 which is rotationally connected with the moving block 6 rotates with the moving block 6 and moves towards the moving direction of the moving block 6, the other end, far away from the moving block 6, of the moving rod 7 rotates with the adjusting plate 8 and simultaneously drives the adjusting plate 8 to move along the direction perpendicular to the axis of the threaded rod 5, in the process, the adjusting plate 8 slides with the inner side wall of the adjusting chamber 4, the knee pad is sleeved on the workbench 2, the distance between the side face, far away from the threaded rod 5, of the adjusting plate 8 and the side wall of the workbench 2 changes to achieve size change of the workbench 2, and after the size of the knee pad is adjusted to be suitable for processing, the adjusting knob 9 is pushed towards the direction of the workbench 2 until the limiting sleeve 12 is matched with the limiting groove 13 again to limit the workbench 2.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
